Overview
be quiet !
The ultimate in quietness for outstanding performance
The be quiet! Straight Power 11 modular power supply offers quiet operation without compromising on quality. Certified 80PLUS Platinum, it offers excellent energy efficiency. An ideal choice for quiet configurations, multi-GPU configurations, multimedia systems and systems for 3D photo/video applications.
Thanks to its fully modular management, the Straight Power 11 Platinum 's cables that serve no purpose in the system are left out. As a result, the system always looks very tidy. Due to the less cluttered layout of the system, the air flow is more fluid, which means less noise and heat inside the housing. In addition, installation is much easier.
SilentWings 3 fan
The high-end SilentWings 3 fan delivers superior airflow with very little noise. Thanks to its unique and optimised blade design, durable dynamic fluid bearing system and 6-pole motor, this fan eliminates operating noise, with the added bonus of minimal energy consumption and a very long service life. In addition, the funnel-shaped fan opening allows for increased airflow resulting in higher cooling performance.
80PLUS Platinum Certification
The be quiet! Straight Power 11 Platinum is 80+ Platinum certified, with a maximum efficiency of 93.7% to 94.1% depending on the model. The main advantages are low power consumption and better cooled, quieter operation.
Wireless design inside the power supply
The Straight Power 11 Platinum power supply operates wirelessly on the DC side inside the power supply unit. This results in improved cooling airflow and limited signal disruption due to the elimination of cables. This innovative design also results in longer component life.

A power supply for my new setup
I took this power supply, because my old 850W 80PLUS Gold can't make my new configuration work with an I9 13900KF and my RTX2080, everything works fine with it, no problem since and it is stable

Explosion of a component after 6 months
Explosion of a component after 6 months at the start-up one morning. Too bad it will have to be dismantled and replaced.

Excellent product
Bought to replace a Seasonic G12-GC-850 which was too noisy for my taste, this BeQuiet does its job perfectly. It is inaudible under low load, and remains very discreet in intensive use.
The modular aspect is very appreciable, the interior of the PC is better arranged, and therefore better ventilated.Review automatically translated -

Good silent power supply to buy with your eyes closed
A lot of connectivity provided in a modular way (far too much for my needs)
A powerful integrated fan that is surprisingly quiet.
In short, the brand promise is kept. Nothing to complain about.Review automatically translated -

Quiet, no coil whine
I use it to power a CPU i7 9700K, a GPU RTX 2070 Super, a CM Asus Rog Strix Z390-E GAMING and 2 SSD's.Nothing to say about the silence, the power supply bears the name of the brand well.Moreover, I have no worries about coil whine.This is the main reason for my purchase, to have a silent power supply. This Straight Power 11 850W fulfils its role perfectly in my case.I take away 1 star because the cables are horrible to handle, much too rigid.My CM was already mounted in its tower with the ventirad of the same brand, a Dark Rock Pro 4. The ventirad was huge, so it was a pain to plug in the cable to power the CPU.

Very good
Used to power a 3700X coupled with a 2080 RTX Super.
Almost nothing to complain about, you can't hear it. After Be Quiet are known for their silence, and I confirm, you can't hear anything.
I only put nine because of the cables: their rigidity is such that, depending on the case, you can succeed at the first attempt or have enormous difficulty connecting them once the motherboard is screwed in.
I personally had a lot of trouble plugging in the cables and getting a "clean" case (with a good cable management). And yet it is a Be Quiet case.
LDLC, please offer a Cablemod type cable configurator (flexible), I would buy directly.Review automatically translated
